Everything You Need to Know About Home Appraisals

In my 45-plus years selling real estate in Napa Valley, I've watched home appraisals derail transactions that seemed solid, and I've watched sellers and buyers navigate them smoothly because they understood what was coming. The appraisal is one of the most consequential steps in any transaction, and yet it's the one most people understand the least going in. Whether you're listing a property along the Silverado Trail or buying your first home in downtown Napa, here is what you need to know.

Key Takeaways

  • A home appraisal is an independent professional estimate of a property's fair market value, ordered by the lender to confirm that the amount being borrowed does not exceed what the home is actually worth.
  • Appraisers evaluate the property's condition, size, layout, and features alongside comparable sales in the area. In Napa Valley, where properties vary significantly in character, the comp selection process is particularly important.
  • If an appraisal comes in below the agreed purchase price, the buyer and seller have options: renegotiate the price, make up the difference in cash, or walk away under an appraisal contingency.
  • Sellers can take meaningful steps before the appraisal visit to support a strong outcome without influencing the appraiser's independent judgment.

What a Home Appraisal Actually Is

The basics every buyer and seller should understand:

  • An appraisal is a professional, third-party opinion of a home's market value, conducted by a licensed or certified appraiser. Appraisers are independent: they do not represent the buyer or seller, and their obligation is to arrive at a fair and accurate valuation.
  • According to the National Association of Realtors, when financing is involved, lenders require an appraisal to protect themselves from lending more money than the property secures. The buyer typically pays the appraisal fee, which runs between $300 and $500 for a standard single-family home, and can be higher for larger or more complex properties.
  • An appraisal is not the same as a home inspection. An inspector evaluates the physical condition and functional systems of a property. An appraiser determines market value, using condition as one of many inputs alongside location, size, comparable sales, and broader market trends.

What Appraisers Look at During the Visit

The walk-through covers more than most people expect:

  • The appraiser inspects the interior and exterior of the property, noting the number and size of rooms, the condition of major systems, the quality of finishes and upgrades, and any visible deferred maintenance.
  • Square footage is measured and confirmed. Layout and functionality matter as well: a modern, open floor plan that buyers want may support a higher value than an outdated configuration of the same size.
  • Renovations and improvements are documented. Updated kitchens and bathrooms have the most consistent positive impact on appraised value because they represent the areas where buyers most directly experience quality.
In Napa Valley, where a property might have vineyard views, a detached guest house, a wine cave, or agricultural acreage, the appraiser must also weigh features that have limited direct comparisons in the market. This is one reason local expertise matters when choosing your representation.

How Comparable Sales Shape the Number

Comps are the backbone of the appraisal:

  • After the site visit, appraisers research recent sales of comparable properties, typically referred to as comps, to anchor their valuation. At minimum, three closed sales within the past six months are used. They must share meaningful characteristics with the subject property in terms of size, location, condition, and features.
  • In Napa Valley, finding truly comparable sales can be challenging given the diversity of the housing stock. A property in Yountville with vineyard views and a pool is not easily compared to a property of similar square footage in a different part of the valley. The appraiser must make adjustments, and those adjustments significantly influence the final number.
  • Broad market conditions also factor in. When interest rates shift or inventory tightens, those forces affect what buyers are paying, and appraisers account for current market direction in their analysis.

What Happens if the Appraisal Comes in Low

A low appraisal does not have to end the transaction:

  • If the appraised value falls below the agreed purchase price, the lender will not approve a loan for the full amount. At that point, the buyer and seller have several paths forward: renegotiate the purchase price to align with the appraised value, have the buyer pay the difference in cash above the loan amount, or contest the appraisal through a formal reconsideration of value request.
  • A reconsideration of value allows the lender to submit factual information that may have been overlooked — incorrect square footage, a missed comparable sale, or features that were not properly credited. Only one reconsideration may be submitted, and the appraiser is not required to change the value.
  • Buyers who included an appraisal contingency in their offer have the ability to walk away without losing their earnest money if the appraisal cannot be resolved.

How Sellers Can Prepare

There are practical steps worth taking before the appraiser arrives:

  • Address visible deferred maintenance. Chipped paint, broken fixtures, damaged flooring, and signs of water intrusion all factor into condition assessments and can drag a number down unnecessarily.
  • Compile a list of improvements made to the property, including dates, costs, and permits where available. Updated kitchens, new roofing, HVAC replacements, and significant landscaping work should all be documented for the appraiser.
  • Make the property accessible and presentable. While appraisers are trained to look past clutter, a clean, well-maintained home conveys care and signals that major systems have been attended to.
